The invention relates to a novel high power
water load. The novel high power
water load comprises a
waveguide radiation horn mouth, a base, a spiral water chamber, a terminal
short circuit block, and a protection housing disposed on the outer side of the spiral water chamber. Spiral type flowing water used as a
microwave absorber is disposed in the spiral water chamber. The front end of the spiral water chamber is in the shape of a cone, and the rear end of the spiral water chamber is in the shape of a cylinder. One end of the
waveguide radiation horn mouth is fixedly connected with an output
radiation waveguide, and the other end of the waveguide radiation horn mouth is connected with the base. The other end of the base is connected with the rear end of the spiral water chamber and the bottom part of the protection housing, and the side of the base connected with the spiral water chamber is provided with a groove embedded in the rear end bottom part of the spiral water chamber. The side of the rear end of the spiral water chamber connected with the base is a water inlet, and the side of the front end of the spiral water chamber is a water outlet. The front end of the terminal
short circuit block is in the shape of a cone, and is embedded in the front end of the spiral water chamber, and the rear end of the terminal
short circuit block is connected with the top part of the protection housing. The
water load is capable of satisfying use requirements of a high power
millimeter wave electric vacuum device, and at the same time, the
broadband low reflection of the water load is realized.
